LEO GROSSMAN, OF BROOKLYN, NEW YORK.

CASTING-BOX.

S EC CA N forming part of Letters Patent No. 690,270, dated December 31, 1901.

Original application filed February 5, 1901, Serial No. 46,056

Be it known that I, LEO GROSSMAN, a citizen of the United States, and a resident'of the city of New York, borough of Brooklyn, in the county of Kings and State of New York,- have invented a new and Improved Casting- Box, of which the following is a full, clear, and exact description, this being a division of the application for Letters Patent'of the United States, Serial No. 46,055, filed by me on February 5, 1901.

The object of the invention is to provide a new and improved casting-box arranged to permit of casting a plurality of stereotypes or the like at one and the same time, so that a large number of stereotypes are produced by the same machine in a comparatively short time.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is an end elevation of theimproveinent. Fig. 2 is an enlarged sectional plan view of one of the cores in a drag, the section being on the line 2 2 in Fig. 5. Fig. 3 is an enlarged cross-section of the improvement. Fig. l is a longitudinal sectional elevation of the same on the line 4 .1c in Fig. 3. Fig. 5 is an enlarged sectional side elevation of one of the cores in a drag, the section being on the lines 5 5 in Figs. 2 and 6; and Fig. 6 is an end elevation of the same. 1

On asuitably-constructed frame A are bolted or otherwise secured the drags B B B arranged one alongside the other and semicircular in cross-section, and in conjunction with these drags operate the cylindrical cores 00, having arms 0 0 respectively attached to rock-shafts D D, journaled in the frame A between adjacent drags and rocked simultaneously to swing the cores simultaneously in or out of the drags, the arrangement being such that each core alternately occupies the two drags located on opposite sides of its rock-shaft, and the drag B between the two rock-shafts D D is alternately engaged by Divided and this application filed June 19, 1901. fierial (No model.)

the cores 0 0. As the cores are cylindrical and the axes of the shafts D D extend in the same plane as the centers of the semicircular drags-B B B it is evident that the opposite faces of each core alternatelyengage adjacent drags, so that while one face is in a drag for making a plate the other face is on top, and

the previously-cast plate on said other face can now be removed therefrom. Now by the use of these three drags and two cores, as shown in Figs. 1 and 3, two plates can be simultaneously cast, while the two plates previously cast can be removed from the cores, so that an exceedingly large number of plates can be produced in a comparatively short time.

In the bottom of the drags B B B are adapted to rest matrices E E E of paper or other suitable flexible material, and each ma trix is secured at its sides on matrix-holders F, adapted to be seated on the sides of the drags and actuated from cams G, secured on shafts H, connected by suitable gearing I with each other and with the main shaft J, connected by pulleys and belts with other machinery for imparting a continuous rotary motion to the shaft J and by the gearing I to the shafts H, so that the cams G thereon operate the matrix-holders F in unison with the cores 0 O, likewise actuated from the main shaft J and the mechanism connecting the said shaft J with the shafts D D. This mechanism consists, essentially, of pinions K, secured on the ends of the shafts D D and in mesh with segmental gear-Wheels L, secured on shafts N, carrying arms 0, pivotally connected with slides P, mounted to slide in bearings P and engaging cams Q, attached to the main shaft J, so that when the latter is rotated the cams Q impart a sliding motion to the slides P, and the latter by the arms 0 impart a rocking motion to the shafts N and the segmental gear-wheels L, so that the pinions K are turned to simultaneously rock the shafts D D, and thereby swing the cores 0 C alternately in or out of the drags B B B as previously explained. The cams Q, are so shaped that the rock-shafts D D are intermittently rocked on the continuous rotary motion of the main driven shaft J, and the cams G are so shaped that the matrix-holders F are intermittently actuated, and said cams G are so constructed relatively to each other and to the cams Q that one matrix-holder and the free end of a core is moved outward more quickly than the other matrix-holder at the time the core begins to swing outward away fromits drag. The matrix-holders are adapted to be opened and closed for convenient insertion or removal of a matrix, and for this purpose the operator actuates the handled levers R, suitably connected with the matrix holders, so that the latter are opened or close to release or clamp the matrices.

At one end of each core is arranged an annular flange S for closing the corresponding ends of the drags, into which the core swings alternately, the flange engaging pins S in the bottom of the drags and also the ends of the matrices, the ends of which abut against the pins S, as is plainly shown in Fig. 4c.

The metal is poured into each drag through sides T, formed in end-gates T, approximately semicircular in shape, each core being provided with two such end-gates T, held movable endwise on core extensions T (See Figs. 5 and 6.) Each end-gate T serves to close the corresponding end of the drag into which the core extends at the time and to engage the end of the matrix of this drag, so that the matrix is securely held in position on the bottom of the drag. (See Fig. 5.) Each core is provided with two extensions T on which the gates are mounted to slide independently of one another, and each endgate on a core is provided with a transverse shaft T extending througli elongated slots T in the sides of the extensions T The shaft T is engaged by a slotted lever T fulcrumed at T on the corresponding extension T and provided at its free end with a handle T adapted to be taken hold of by the operator to impart a swinging motion to the lever T and move the gate T inward or outward. It is understood that a gate of a core is moved inward to close the metal-pouring end of the drag soon after the casting has been removed from the top of the core and previous to the core moving into the drag. The metal is now poured into the sides T and flows from the latter into the space between the matrix and the core to form the casting. Asthe two cores engage two drags at a time it is evident that as the metal is poured sim ultaneously into the two drags two plates are cast, and when this has been done the cores swing out of their drags and into adjacent ones, as previously explained, and two additional plates are cast, while the previouslycast plates are removed from the top surfaces of the cores.

From the foregoing it is evident that avery large number of plates can be successively cast in and removed from the mold or casting box, and the matrices can be readily changed Whenever required without disturbing the cores and the parts connected therewith. When two cores are employed, three drags are required but I do not limit myself a plurality of independent drags for engagement by the said core, and means for bringing the said cores in working engagement with the drags in alternation for successively casting separate plates on opposite faces of the core and the corresponding drags and for removing one cast plate whileanother is cast, as set forth.

3. A casting-box having a plurality of drags, a plurality of cylindrical cores for the said drags, and means forbringing the cores and drags in working engagement with one another for casting separate plates on opposite faces of the cores, as set forth.

4. A casting-box having a core, a plurality of drags for engagement by the said core, and means for moving the said core in and out of the drags in alternation, one drag being in position to receive approximately one half portion of the core and the other drag being in the path of the other half portion of the core for successively casting separate plates on opposite faces of the core and the corresponding drags and for removing one cast plate while another is cast, as set forth.

5. A casting-box havinga plurality of cores, a plurality of drags, and means for moving the said cores in and out of the said drags in alternation, as set forth.

6. Acasting-box having a plurality of cores, a plurality of drags, and means for moving the said cores in and out of the drags in alternation, the position of one of the drags corresponding to one position of each of the cores to receive the cores in alternation, as set forth.

7. A casting-box havinga plurality of drags arranged one alongside the other,a cylindrical core for the said drags, and means for swinging the core in and out of the drags in alternation, as set forth. 8. A casting-box havinga plurality of drags arranged one alongside the other, a core pivoted between the said drags, and means for swinging the core in or out of the drags in alternation, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

LEO GROSSMAN.
